Addition and subtraction games for kids
The two first worlds in the practice library are addition and subtraction games for children from age 5. They use the same levels, so a child can play one stage of each and see the same numbers from both sides.
- Number Grove: addition games. How many altogether? Counters for small sums, then counting on and splitting numbers into easier steps, up to three-digit totals.
- Subtraction Shores: subtraction games. How many are left? Counting back, with an adding-back check on every answer and never a negative number.
When your child is ready for more
- Multiply Mountain: multiplication math games and times tables up to 12 × 12, from age 7.
- Fraction Falls: fraction math games, from naming parts of a shape to equivalent fractions, from age 7.
- Two-player maths games for two children or a parent and child on one device.
Find your child’s grade or Year
- 2nd grade math games: Adding and subtracting within 100, equal groups and halves, thirds and fourths.
- 3rd grade math games: Multiplication facts and a first look at fractions.
- Year 3 maths games: The 3, 4 and 8 times tables, three-digit sums and unit fractions.
- Year 4 maths games: All the times tables to 12 × 12 and equivalent fractions.
- Maths for 7 year olds: What most 7 year olds work on, with questions to try at home.
- Maths for 8 year olds: What most 8 year olds work on, with questions to try at home.
- Choosing a maths app for kids: A parent checklist, and where Clarendium fits.
Questions parents ask
Which game should my child start with?
From age 5, start with Number Grove (addition), then Subtraction Shores (subtraction) at the same level. From age 7, Multiply Mountain and Fraction Falls open too.
Why practise addition and subtraction together?
They are two sides of the same fact: if 7 + 5 = 12, then 12 − 5 = 7. Every Subtraction Shores answer is checked by adding back, so practising both builds number facts faster than either alone.
How do I change the level?
Use the practice level menu at the top of this page, or settings. Choose a US grade (Kindergarten to 5th grade) or an England Year (Year 1 to Year 6).
